SHAKER. i

Specification of Letters Patent.

Patented Feb. 22, 1910.

Application tiled March 26, 1909. Serial No. 485,920.

To all 'whom it may concern.'

Be it known that I, CARL'RTNER, a citizen of' the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in Shakers,of which the following is a specification,- reference being had to theaccompanying drawing, forming a part thereof.

This invention relates to devices for shaking and sprinkling salt,spices or other sub-V stantially dry powdered lo r comminutedsubstances. Its main objects are to insure free delivery of suchsubstances from the receptacles containing them, to provide means forregulating or adjusting the delivery thereof; to avoid contactl of thecontents of such receptacles with metal; to prevent obstruction of thedischarge orifices of such receptacles; to prevent the contents of suchreceptacles from absorbing moisture from, or being contaminated by openexposure to the atmosphere; and generally to improve the constructionand operation of devices of this class.

In the accompanying drawing like characters designate the same parts inthe several figures.

Figure 1 is a side view of a salt or spice shaker embodying theinvention in a form for table use; Fig. 2 is a central vertical sectionof the same on the line 2 2, Fig. l; and Fig. 3 is a similar section onthe line 3 3, Fig. 2, of a portion of the shaker, showing the sameinverted and the ball slightly removed from its seat.

The shaker comprises a receptacle a, which for table use :for salt,pepper or the like, is preferably made of glass' or some nonmetallicmaterial. Like an ordinary table salt shaker or pepper box, it has acircular mouth or opening at the top and an externally screw threadedneck Z) around the mouth or opening. A ball c, of somewhat largerdiameter than the diameter of the mouth or opening of the receptacle,fits partially. into and normally closes the same when the receptaclestands in an upright position, as shown in Figs. l and 2. For use withsalt or other substances which have a corrosive effect on metal, theball is preferably made of glass or of some nonmetallic material. Theball is loosely confined over the mouth or opening of the receptacle bya keeper consisting of a collar d, removably threaded on the neck b andprovided with an upwardly arched yoke or cross piece e. To regulate orvary the area of the discharge orifice between the ball and its seatwhen the receptacle is inverted or tipped and shaken, the yoke or crosspiece e is provided with an adjustable abutmentl or bearing for theball. This abutment or bearing may consist as. shown, of a thumb screw fthreaded in the cross piece centrally with relation to the collar d, asshown.

lVhen the shaker is not in use and stands in its normal position asshown in Figs. 1 and 2, lthe ball resting upon its seat in the mouth oropening of the receptacle, closes the receptacle and prevents exposureof its contents to the outside atmosphere. This is of special advantageto salt or other deliquescent substances which absorb moisture from theatmosphere.

In operation, when the receptacle is inverted or tipped and shaken, theball dropping from its seat against the point of the screw f, as shownin Fig. 3, leaves a narrow opening around it for the escape of thepowdered or comminuted contents of the receptacle. The movement of theball between its seat and the point of the screw produced by theshakingof the receptacle, interrupts the' How of material from thereceptacle, causing it to issue therefrom in a spray or finelydistributed condition. It also prevents incrustation of the material,such as salt, on the ball or its seat, and keeps the discharge orifice:free and clear from obstruction. The area of the discharge orifice isreadily varied to afford a freer or more restricted delivery, by theadjustment of the screw f. To ll or refill the receptacle, the collar dof the keeper is unscrewed from the neck I), and the ball is removedfrom the mouth or opening in which it is seated.

Various materials may be employed in the construction of the shaker, andvarious modifications may be made in details of construction Withoutdeparting from the principle and scope ofthe invention.

I claim: y

1. In a shaker for powdered and comminuted substances the combination ofa receptacle having a circular discharge opening, a ball fittedin andnormally closing said opening, and a collar detachably secured to saidreceptacle around said openin and having a cross piece loosely confnmgsaid ball in lace over said opening and adapted to hold) it in positionto leave but a narrow orifice between it and its seat when saidreceptacle is inverted.

`nuted substances, the combination of a nonmetallic receptacle having acircular mouth 15 or opening at the top and an externally screw thleadedneck around said opening,"

a nonmetallic ball fitting partially into and normally closing vsaidopening, and acollar removably threaded on said neck and having a crosspiece adapted to loosely confine said ball 'over said opening positionto leave but a narrow orifice between it and its seat when saidreceptacle is inverted.

In witness whereof I hereto aiix my signature in presence of twowitnesses..

CARL ARTNER.
